It's the Rim of the galaxy, and once you come out of hyperspace
past the galactic rim, all your points of reference are gone, and
getting back is tough, if not impossible...and you can't just "keep
going" in a straight line in hyperspace, as it's not a one-to-one
corrolation to normal space.

No, the events take place only in our own galaxy, and only in
portions of that...it's just too big a place.
